POTATO-PLANTER.

SPECIFICATION forming part of Letters Patent No. 503,695, dated August 22, 1893.

Application filed November 37(7), 1892. Serial No. 453,562. (No model.) A

To all whom t may concern.-

Beit known that I, ELTON FAY CHUBBUCK, a citizen of the United States, residing at Haskinville, in the county of Steuben and State of New York, have invented certain new and useful Improvements in Potato-Planters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in planters, and has for its object the provision of such a d evice as will be particularly adapted to the planting of potates, so that the latter can be placed in a hopper without any previous preparation,and fed into a cutting box in which they are cut into suitable pieces for seed and conveyed therefrom and deposited in a furrow at suitable intervals.

The invention consists primarily of a cutting box in which a longitudinal passage is formed through which a conveyer moves, of a knife secured in the said box parallel with the con.- veyer and flush with the top of the passage, the conveyer being adapted to draw a potato which may project into a bucket of the same against the knife to sever the portion contained in the bucket and to carry the same to a depositing spout, into which it is forced by a spring.

It consists secondarily of the peculiarly constructed mechanism whereby the several parts hereinbefore mentioned, and their ad- Juncts are supported and operated,which construction as well as that previously mentioned, will be hereinafter specifically described, pointed out in the appended claims and illustrated in the accompanying drawings.

In the accompanying drawings in which similar letters of reference designate corresponding parts, Figure l is a plan view of a planter embodying the invention. Fig. 2 1s a side elevation of the same, being partly in section. Fig. 3 is a section on the line 3-3 of Fig. 2. Fig. 4 is a detail view, showing a longitudinal section of the cutting box, the conveyer, the spring for forcing the seed from the links of the conveyer, and several of their adjuncts. Fig. 5 is a detail view showing a side of one of the links forming the conveyer. Fig. 6 is a similar view showing the opposite side of the same. Fig. 7 is a detail perspective View showing one of the links complete, and Fig. 8 is a detail perspective view showing the plow or furrow opener.

Referring to the drawings by letter, A designates the main frame of the machine of any construction suitable in the premises, mounted near its rear end upon the shaft B carried by the wheels O, O, the said wheels being keyed on the said shaft so that the latter will be rotated with the former, and has attached to its forward ends the thills D, D or any other suitable deviceforiprppulsion.

As one side of the machine is an exact duplicate of the other, only one will be described, as the same description can be applied to both.

E designates a hopper mounted on an extension of the main frame outside and in advance of the carrying wheel. The hopper may be of any construction adapted to feed the potatoes into a cutting box F attached to its lower end. The cutting box has its front and rear sides cut away to form a passage, the purpose of which will be explained farther on. To the front side of the cutting box, a knife G is attached with its blade parallel with the passage, and its under face iiush with the top of the same.

H and H designate two sprocketwheels respectively mounted on the ends of the shaft B and B; the former being loosely mounted and the latter being keyed in place. The sprocket wheels carrya conveyer or sprocket chain I consisting of rectangular shaped links t t, a side of each link being extended to form a hook t2 adapted to engage with a loop 3 formed in the extension of the adjacent side of a preceding link. The chain or conveyer is so mounted as to pass through the passage of the cutting box and its size is such as to completely fill the said passage, and the top of each link to pass immediately below the knife. A plate J is secured on the frame immediately below the cutting-box so as to support the chain in its proper position on its passage through the cutting box and over the depositing spout.

K designates the Vdepositing spout which IOO , carriedV forward until the link isin registerl of the wheel C. To the front face of the lower end of the spout, the plow or furrow opener L is secured. This opener (see Fig, 8)has,sub,v stantially, a triangular shape at its forward end, and its rear end consists of two parallel sides adapted to partly inclose the end of the spout. The rear lower face of the spout is cut away, as at k, to allowafree egress of the seed. The'spoutgissupported against longi` tudinal strain by the braceslo 7o. Y

S designates a U-shaped spring, with one of the limbs much longer than the other and fastened to the front of the cutting'box and hopper, the long. limb allowing, the limb-to be securely fastened inplace. The springi'sso placed and of'such asize as to force, itself into the links as they successively come beneath it, the contactingsurface ofthe spring being rounded so that but slight resistance isfoifered to the passageA of the chain- Y On the driving shaft B is keyed'the sprocket wheel a and on the shaftv M, mounted parallelV withand intermediate ofthe shaftsB and" B;

are keyed'the largel and small sprocket wheels a andl a2'and-upon the shaft B is keyed the large sprocket Wheel a3. The Wheel a is con.- nected with the wheel a', and `the wheelol.2 with the -wheel a3 4by the sprocket chains d4 and a5, respectively. Through this mechanism. motion given to the shaft Bf will be conjveyed tothe shaft B and consequently to the sprocket chain or conveyer I to movethelata ter forward beneath the hopper.

The-operation ofthe device isas follows:

The hopper being previously filled withpot'atoes, the machineis put in motionand through l the connecting mechanism the sprocket chainor conveyer I is made to move through vthe. One of the-potatoes will,when

cutt'ingbox. alink of the chain isin register with the cut'- tingebox, drop into the link, and "as lthe latter advances, the potato will be drawn against l the knife and a portion of it'severed. As the chain progresses the piece of" potato will be with the depositing spout, Yinto which it` will drop or be forced by the spring S and thereby be connectedV to tliefurrow opened by the plowland then be covered by the wheel G.-

The gears and their adjuncts whichfconneet the shafts B andB are so formed and connected that the passage of a link through the cuttingbox willi' be so timed' as to deposit thel seed at the desired intervals.

Having` thus described my inventionwhat. yeyer moving through the said* passage, the
